UNITED STATES JOHN A. LANNERT, OF CLEVELAND, OHIO.

rnnss FOR FORMING TILE BLANKS.

Application filed October 3, 1925.

5! '0 all whom it may concern:

Be it known that 1, JOHN A. LANNERT, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Presses for Forming Tile Blanks, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that princie ple, so as to distinguish it from other inventions.

The presentinvention relates to machines for punching and cutting tile blocks. More particularly the present mechanism is adapted for forming the end reinforcing tile plates such as are shown in my United States Letters Patent No. 1,365,705 dated Jan. 18, 1921. These end plates or blocks are used in connection with hollow tile and are preformed and are then either hardened by burning as individual units and set up with the tile with mortar or cement or are air dried and then insertedin one end of the tile and are baked or hardened therewith into an integral unit. In making such rectangular end plates, they are first extruded and cut to shape and the present machine is adapted to finish the block by punching the centrally disposed aperture and at the same time notching the projecting ribs on both sides of the plate so that it may readily fit the building block. To the accoinplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and thefollowing description Set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may housed.

in said annexed drawings Fig. 1 is a front elevation of the machine; Fig. 2 is a side elevation of the machine;

Fig. 3 is a plan view; Fig. 4c is a horizontalsection on the line 4@ of Fig. 1;Fig. 5 is a perspective view of the extruded blank before it is passed through the machine; Fig. 6 is a perspective view of the finished blank; Fig. '7 is a sectional view through a hollow tile with the blank mounted therein; Fig. 8 is a section similar to Fig. 7 but showing the blank reversed and held in place by a mortar joint; Fig. 9 is a fragmentary secerial No. 60,186.

tion showing a modified form of cutter in place; Fig. 10 is a front elevational view of the cutter shown in Fig. 9; and Fig. 11 is a sectional view through the cutter head shown in Fig. 9 showing the relation of the cutter and wedge member.

The present invention comprises a base or table 1 having legs 2 and having an upright guideway 3 in which is slidably mounted a.

cross head a. At the top of the guideway is mounted a drive shaft 5 having a driving pulley 6 and an eccentric 7 mounted the connecting rod 8 which at its lower end is pivotally attached to the cross head pin 9. The other end of the shaft-extends beyond its bearing 80 and is provided with a pair of eccentrics 10. Attached to the cross head is the die or plunger 11, the table top being apertured as at 12 to allow the plug cut from the blank to drop through the table. On each side of the table are a pair of bosses 13 in which are mounted rock shafts l t on which are rocker arms 15 connected to the eccentrics 10 by means of rods 16. Each shaft 14 is also providedwith a crankl? pivotally connected to a push rod 18.

Mounted longitudinally of the table top is a guide strip or track 20 which is provided at the front with an aperture 81 aligned with the aperture 12 in the table top. On each side of the table top are a pair of guide blocks 21 in which are slidably mounted cutter heads 22 transversely movable by means of the push rods 18 to which they are pivotally connected. These heads are provided with a series of cutters 23 and 24, the cutters 23 at the ends of the heads being formed of angles while the center cutter 24 on each head is of channel section. The cutters 23 at the top of the head are identical with the bottom cutters 23 except that they are reversed as to position so as to out a corresponding notch on each side of the blank. The center cutters 2d are also alike but the top cutter is open at the top and the lower cutter at the bottom. The guide strip or track 20 is notched to provide recesses 25 into which the cutters may pass. Mounted.

over the cutters is a cover plate 26 which has two longitudinally extending ribs 27 forming an upper track and the plate has a slot 28 to allow downward movement of the plunger or die.

The blanks 30 on which, the machine is to operate are best shown in Figs. 5 and 6,

on which is the blanlt as shown in Fig. 5 beingrectangular in shape and being provided with a pair of ribs 31 and 32 on each face, the ribs 31 being spaced apart farther than the ribs 32' on the other face. These blanks are formed, preferably extruded on a separate machine and are then mounted on the track at the rear of the machine with the ribs'31 fitting the sides of the guide strip. A lever 35 is pivot'ally mounted on the table top and is provided with a roller 36 adapted to engage a blanli so as to move it forwardly of the machine. A-n adjustablestop 37 is mounted on the table and so positioned that movement of the lever will force theforwaid one oftwo blanks in position under the plunger and opposite the transversely movable cutters. The next blank and movement of" the lever will position the secondblanlc and move the first blank out to the front of the table for removal; In its finished form the block is best shown in Fig, 6 with the ribs 31 and 32, cut away at the ends and with notches at the center. This allows the blanks to be inserted in the hollow tile either as shown in Fig. 7 where the ribs fit snugly into the tile for burning or hardening into an integral'unit or as shown in Fig. 8 where the tile andblock or plate are hardened separately and then secured together by mortar or cement filling 40. The blank is also preferably suppliedv with a groove or recess 41' for the-insertion of a tool or wedge to pry the blocks apart after hardening.

In Figs. 9' and 10, a modified cutter arrangement isshown, themovable cutter head 69 having only two sets of cutters 70 and 71', the cutters TOlocated centrally and the cutters 71 at the rear end of the-head. Both sets of' cutters are. of channel shape andv the cutters 7 1' are so placed that they overlap-the two blanks andtlius out the rear notches in: the front blank and the front notches in the rear blank at one stroke; The heads. 69" are. provided with slots 72' to receive the cutter blades, each cutter being. made up of' three adjust-able cutter blades, 75*a-nd' 76, the bottom blade 75 fitting the bottom o-f'the slot, while the two blades76' stand vertically along. the sides of the slot, being held in the desired spaced adjusted relation by a wedge 151001177 which'is mounted adj acent' thetop of the blades leaving an opening78 for the cut portions of the'ribs to pass througlt A coverplate 73 is mounted over the blades and'is secured to the head by means of screws and'this plate is adapted to bear againstthe upper edges of the blades 76 to aid'in holding them in, position. I

The operation of the machine is carried on'in the usual way, the drive shafts being fitted with the usual type of clutch adapted torotate the shaft one full revolution after the clutch is tripped. Such trip" may be pedal or lever actuated or may be so placed that the? blank moving lever will trip the clutch as it moves to its final in position against the stop. The blanks are thus pui'i'cl'ied and the"- ribs out and slotted in one operation and the movement of the next blanle intoposition to be operated upon forces the completed blank out on the table where it maybe easily removed. The guide strips prevent the ribs from being bent or distorted during the cutting by the transverse 7 cutters @ther modesofapplying the principle of my invention may be 'en'iplo'yed' instead of the one explained, change being mafde" asregards the mechanism herein disclosed, provi'ded' the means stated by any of the fol lowing claims" or" the equivalent of' such' stated meansbe employed. 1
